[0023] As Figures 1-4 shown, the driving component 34 of this embodiment includes a swing rod 341, an eccentric shaft 342 and a connecting part 343. The eccentric shaft 342 is fixedly connected to the side of the turntable 33 away from the motor 32. The eccentric shaft 342 is eccentrically arranged with respect to the rotating shaft of the motor 32. The middle part of the swing rod 341 is rotatably connected to a shaft rod 6 perpendicular to the rotating shaft of the motor 32. Both ends of the shaft rod 6 are fixedly connected to the side wall of the handle 1. A through sliding hole 3411 is arranged on the side of the swing rod 341 close to the turntable 33. A sliding column 7 is slidably arranged in the sliding hole 3411. The sliding direction of the sliding hole 3411 is parallel to the axis of the shaft rod 6. A connecting hole 3412 communicating with the sliding hole 3411 is arranged at one end of the swing rod 341 close to the sliding hole 3411. A jack 71 adapted to the eccentric shaft 342 is arranged on the side wall of the sliding column 7. The eccentric shaft 342 passes through the connecting hole 3412 and is embedded in the jack 71. A concave bayonet 221 is arranged on the lower side of the middle part of the moving blade 22. A through strip-shaped groove 3413 is arranged on the side of the swing rod 341 away from the motor 32. The length direction of the strip-shaped groove 3413 is the same as the length direction of the swing rod 341. The connecting part 343 includes a horizontal connecting rod 3431. One end of the connecting rod 3431 is provided with a dial rod 3432 extending towards the bayonet 221 and embedded in the bayonet 221.

The sliding rod 3433 is slidably arranged in the strip-shaped groove 3413 and extends out of the strip-shaped groove 3413. Gaskets 3435 are respectively sleeved on the sliding rod 3433 on the upper and lower sides of the strip-shaped groove 3413. Springs 3434 are respectively sleeved on the sliding rods outside the two gaskets 3435. An adjusting nut 3436 is screwed on the end of the sliding rod 3433.

[0024] The swing rod 341, the sliding column 7, the turntable 33 and the eccentric shaft 342 are all made of engineering plastics. Using engineering plastics for the above components has a good self-lubricating effect during their movement, eliminating the need for additional lubricant addition, improving the service life of the product, and reducing the noise generated during movement.

[0025] By sleeving gaskets 3435 and springs 3434 on the sliding rods 3433 on the upper and lower sides of the strip-shaped groove 3413 respectively, the springs 3434 above the strip-shaped groove 3413 abut against the gaskets 3435 and the connecting rod 3431 respectively, and the springs 3434 below the strip-shaped groove 3413 abut against the gaskets 3435 and the adjusting nuts 3436 respectively; by adjusting the adjusting nuts 3436, the elastic force of the springs 3434 can be adjusted, and the stable and reliable dynamic connection between the swing rod 341 and the moving blade 22 is ensured through the connecting portion 343.

[0026] When the motor 32 works, the rotating shaft of the motor 32 drives the turntable 33 to rotate, and the eccentric shaft 342 on the turntable 33 drives the sliding column 7 to slide up and down and rotate in the sliding hole 3411. Since the eccentric shaft 342 is disposed offset from the rotating shaft of the motor 32, the circumferential rotation of the eccentric shaft 342 drives the swing rod 341 to swing reciprocally about the shaft rod 6; the front end of the swing rod 341 swings in an arc shape reciprocally, and the two side walls of the strip-shaped groove 3413 push the sliding rod 3433 to swing linearly reciprocally. At the same time, the strip-shaped groove 3413 also reciprocally slides along its length direction with the sliding rod 3433, converting the arc-shaped reciprocating swing of the swing rod 341 into a linear reciprocating swing of the sliding rod 3433; the linear reciprocating swing of the sliding rod 3433 drives the moving blade 22 to swing linearly reciprocally along the width direction of the fixed blade 21 through the connecting rod 3431 and the toggle lever 3432.

[0027] As Figure 1 shown, the pressing device of this embodiment includes a C-shaped elastic sheet 4. A clamping groove is provided on one side of the inner side of the handle 1 near the upper side of the moving blade 22. One end of the elastic sheet 4 is clamped in the clamping groove, and a strip-shaped pressing groove 222 is provided on the upper surface of the moving blade 22 along the width direction. The other end of the elastic sheet 4 is embedded in the pressing groove 222. The elastic sheet 4 can apply a pressure to the moving blade 22 in the direction of the fixed blade 21, ensuring the close fit between the moving blade 22 and the fixed blade 21 and ensuring the shearing effect; at the same time, during the linear sliding process of the moving blade 22, the elastic sheet 4 can slide in the pressing groove 222 without affecting the pressing effect of the elastic sheet 4.

[0028] By providing the elastic sheet 4, it is ensured that during the reciprocating movement of the moving blade 22, it always fits with the fixed blade 21, ensuring the smooth progress of hair shearing.
